(CNN) -- About 200 firefighters Wednesday evening fought a spectacular fire that lit up the sky in Los Angeles.
A printing facility in Chatsworth, about 30 miles northwest of downtown, appeared to be mostly gutted after the 6 p.m. (9 p.m. ET) blaze.
No injuries had been reported and there were no evacuations, said fire department spokesman Brian Humphrey.
The cause of the fire, which was contained to the large building, was not immediately known.
Firefighters, who poured water on the blaze from ladder trucks, appeared to have it contained within an hour.
